Visible crew/equipment: Just after the police bus pulls over inside the prison, the camera moves forwards towards the side of the bus towards the front whilst one of the guards goes to open the bus door. When the guard walks around the driver side just before reaching the door to open it for the prisoners, the reflection of the camera crew can be seen reflected on the side of the bus. (00:03:10)
Continuity mistake: When Ricky is being inspected for metal by the two prison guards, he opens his shirt so to reveal his chest. His right nipple (or left from the viewer's POV) is exposed, but in a close-up shot of his chest, the nipple is suddenly covered by his shirt. (00:05:28)
Continuity mistake: When the two prison guards discover that there is metal inside Ricky's chest, they begin pushing him over to the X-ray machine. The guard holding a baton is shown pushing the bottom of the baton against Ricky's upper back, but in the next shot, he's suddenly pressing the entirety of the baton against Ricky's back. (00:05:39)
Revealing mistake: When the elderly inmate is pushed over by the other prisoners, a wooden train he made falls out of his clothing. It can be noticed that the man is just holding the train in his hand whilst falling and drops it when he lands on the ground to make it appear as if it fell out of his clothing. He was not meant to be holding the train as it was not shown being held in his hand at any previous point. (00:07:25)

Continuity mistake: When the Captain slashes the elderly inmate's face with an object, the elderly inmate falls over and his left hand is covered in blood.

Revealing mistake: When the Captain is tripped over by Ricky, his face lands on a plank of wood with nails sticking out of it. In the shot of his face getting impaled with the nails, we can see that the Captain has been replaced with a dummy. (00:08:50)
Continuity mistake: At the start of the scene where the two prison guards are telling the elderly inmate that his probation has been rejected, in the establishing shot, he is shown leaning his head forwards sightly. When he begins speaking in the following shot, he is suddenly standing upright. (00:11:20)
Continuity mistake: When the prison guard pushes over the elderly inmate after telling him they rejected his probation, he lands on the ground and his glasses fall off. The glasses are shown right next to him, but two shots after, the glasses are suddenly further away. (00:11:35)
Revealing mistake: When the elderly inmate is telling the two prison guards he wants to go home to see his wife and kids, one of the guards kicks him, and he falls back, but the kick misses the inmate by a few inches. (00:11:50)

Revealing mistake: Uncle Ghost sets a headstone in front of Ricky and tells him to break it with his energy. He breaks a small corner on the headstone with his hand to demonstrate, however it can be noticed that there are visible cut marks on the corner that he breaks off before doing so, revealing that the corner had already been cut off and reapplied to make it easier for Uncle Ghost to chop it off. (00:20:55)
Visible crew/equipment: During the headstone smashing scene, there is a moment right after breaking one with his back, where Ricky does a backflip and destroys a headstone being thrown in the air, and the hand of a crew member can be seen momentarily to the right of shot when it is thrown at him. (00:21:28)
Visible crew/equipment: When Uncle Ghost is throwing headstones at Ricky for him to break, there is a shot of Ricky showing him breaking a headstone by letting it hit him the chest. Here, the hand of a crew member can be seen briefly entering the shot throwing the headstone at him. (00:21:36)
Continuity mistake: Uncle Ghost throws a headstone at Ricky which he catches by punching two holes straight through the middle of and letting the headstone rest on his arms while he keeps his arms raised. In the first shot, both of Ricky's arms are level with each other, but in the next shot, his left arm is suddenly higher up than the right arm. (00:21:45)
Revealing mistake: When the assistant warden stabs Ricky in the hand with his metal hook hand, in the close-up shots of Ricky's hand, it is apparent that Ricky's hand has been replaced with a fake dummy hand. (00:25:08)
Continuity mistake: When the assistant warden is punching Ricky in the face, there is initially no blood shown on his face in the profile shot. When Ricky's face is shown in a close-up, there is blood on his chin, in his mouth and running down his mouth that would have been seen in the profile shot. (00:25:22)
Continuity mistake: Whilst the assistant warden has Ricky's hand trapped in his hook hand, there is a shot where the assistant warden slams his right hand into his hook hand to make it more painful for Ricky. In the next shot of Ricky, both of his eyes are shown wide open. When the shot cuts, his left eye is suddenly squinting and is closed more than the right eye. (00:25:37)
Continuity mistake: When Ricky breaks the assistant warden's desk after getting stabbed through the hand, in the shot of the desk collapsing, strips of tape can be seen on both the left and right hand side of the table. A couple of shots later, just after dodging a bullet, Ricky begins walking over to the assistant warden, and the strip of tape on the left hand side of the table has disappeared. (00:26:28)
